Wolff mainsprings

I have a 1920 DWM luger which I bought a few years ago. As purchased this gun jammed alot, and rarely locked the toggle when empty. New mags and several brands/bullet wt. changes didnt help.
As I could find nothing else wrong with the gun,I did a little research and purchased a Wolff mainspring calibration set. The set included 36,38 and40lb springs + three new striker springs. I also got a pair of extra power mag. springs.
I installed the 36lb spring {quite a task} and presto! The gun works great. Extruded mag, standard mag, aftermarket mag,extra power spring mags,all brands/wts ammo Ihave tried work well.
So heres my question, is the 36lb spring too light for Rem.UMC 115gr. or Win.USA 115gr ammo. Am I going to beat this cool old gun to pieces, or should I try one of the heavier springs.
Any advice appreciated Stevie
